She seems to be incredibly shy and has never talked to anyone at school, making her something of a mystery to her classmates. However, one day, you accidentally stumble into her classroom and catch a glimpse of her without her stickynote.

you saw her rehearsing a idol song and she sung in a nice whispery tone

"Ahhh!! W-who are you? " Rina said with a shy shocked tone.
